To all whom it may concern:

EBe it known that-I, CnA-nLnsdl/I. WVILKINS,

:a citizen of theI-lnited-States, residing at "-Sm-ithfield, in thecounty of 'iFayette. and State of ,Pennsylvania, have invented :new anduseful Improvements in Pullers, of which the following isaspecification.

This invention relates to a puller forrpulling sleeves from shafts andthe like; the general object of the invention. being to provide asupporting member having a movable member therein which carries aprojection for engaging a hole in a sleeve with means for causing thepro ection to engage the hole when the puller is placed in the sleeve sothat the sleeve will be contracted and pulled from the shaft by aturning and pulling movement of the puller.

Another object of the invention is to provide means for locking theprojection in the hole in the sleeve when necessary.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a sectional view showing the invention in use.

Figure 2 is a perspective view of the device.

Figure 3 is a longitudinal sectional view through the outer end of thedevice.

Figure 4: is aview of a sleeve which the device is intended to remove orreplace in ashaft.

As is well known some of the sleeves of certain types of automobiles areconstructed, as shown at A, in Figure 4, so that when placed in a shaftor housing, such as shown at B in Figure 1, the sleeve will expand andthus be held in place by friction and by the engagement of a tip a onthe sleeve with an opening I) in the shaft. It is the object of myinvention to provide a tool for removing such a sleeve from its shaft orhousing and replacing it or another sleeve. In carrying out my inventionI provide a tabular new at i which 13 diameter slightly less thanz-the.sleevetso; that. it can enter; the sleeve. A cross sectional.curvledLstripwQ is 1 placed in tl1e:tubular membertwith ,one end ,heldin placebyaclip 3.:zwhich is;fastenedato the. inner'wa'lluof the member,-and byaaabolti which passes through, a: hole in the tubular member andis fastened to; the strip. spring :5. on thebolt engages a nut 6' there--on so that the :spri-ng tenols to. .hold the strip an;1int'erio'1--,-;pI 1'ti0: v fc the tubu ar member. The strip has aprojection or key 7 having a flat outer surface and which is adapted toengage the oil hole a in the sleeve when the puller is placed in thesleeve. A handle bar 8 is adapted to be passed through holes 9 formed inthe outer end of the tubular member to manipulate the same. A collar 10is placed on the tubular member to form a shoulder.

From the foregoing it will be seen that when the device is placed inasleeve with the shoulder formed by the collar bearing against the outerend of the sleeve the projection or key 7 will be in a position toengage the hole a when the puller is turned to bring said key oppositethe hole. In placing the device in the sleeve the bolt 4: is pressedinwardly so as to swing the strip 2 inwardly and thus bring the outerend of the key 7 flush with the tubular member so that this key will notinterfere with the insertion of the device in a sleeve. When the devicehas been partly inserted the bolt can be released as then the key willsimply slide over the inner wall of the sleeve. When the shoulder formedby the collar strikes the end of the sleeve the device is rotated untilthe key comes opposite the hole when the spring 5 will cause it to enterthe hole. Then by giving the puller a turning movement to the left andpulling on the handle the sleeve will be contracted and withdrawn fromthe shaft. If necessary the nuts 6 can be tightened on the bolt to lockthe key in the hole though this is very seldom necessary.

A new sleeve. can be put in place with this catches the sleeve and as ithas but a few working parts it will last for a long time and will notget out of order.

It is thought from the foregoin descrip tion that the advantages andnove features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the ber and passing through an opening in the tubular member forengaging the oil opening in a sleeve, yieldable means for normallyholding the carrier with the key projecting but permitting the carrierto be pushed inwardly to'retract the key and adjustable controllingmeans therefor included in the yieldable means.

2. A sleeve puller comprising a tubular ,member, ahandle connectedtherewith, a

longitudinally extending strip within the member, a bracket for movablysupporting one end of the strip, a key carried by the other end of thestrip and passing through a hole in the tubular member, a bolt carriedby the strip and passing through the tubular membeiya spring on the boltand a nut on the bolt for adjusting the tension of the spring. tubularmember, a key carried by said mem- In testimonywhereof I afiix mysignature.
